此查询抛出ERROR - [position 0, near 'WHERE' in 'Select path.ePath, path._'] COMMA expected but not found in GROUP BY.
这是我的查询:
Select path.ePath, path._rowid, doc.Filenumber, COUNT(doc.ePathUID) AS children
from docPath path LEFT OUTER JOIN
docMeta doc
ON doc.ePathUID = path._rowid
GROUP BY path._rowid
我期望计算关系的每个孩子,但查询不起作用。我怎样才能使查询工作?
